CVE-2026-112783 Details
Description
OpenCATS before 0.10.0 contains a missing authorization vulnerability in ajax/deleteActivity.php and ajax/editActivity.php that allows READ-level users to edit and delete activity entries. Authenticated attackers can supply an arbitrary activityID via GET or POST to modify or delete activity and pipeline history for candidates, contacts and companies.
A missing authorization vulnerability has been identified in OpenCATS versions prior to 0.10.0, specifically within the AJAX activity management endpoints. This vulnerability allows users with READ-level access to edit and delete activity entries. The issue arises because the 'SecureAJAXInterface' only validates authentication and not authorization. As a result, authenticated users can manipulate activity and pipeline history for candidates, contacts, and companies by supplying an arbitrary activityID via GET or POST requests.
Users can update to OpenCATS version 0.10.0 or later, where this vulnerability has been addressed.
